tearing my hair out here. I've got both a 5700xt and a 7900xtx that wont show up. I've tried every slot it will fit in, and also the others with a pcie riser card and none of them get either card to show up in lspci. I've plugged and unplugged all the power cables dozens of times. I've tried...

Call me crazy, but I'm looking to quiet the server down. I printed out a template to know where to drill

closest I can find is https://www.mouser.com/ProductDetail/KYOCERA-AVX/W2L14D225MAT1A?qs=T8npLvK5duGOD8r%252B3Anvqw%3D%3D but the size I need would be w4 not a w2, but according to their datasheet chart https://www.mouser.com/datasheet/2/40/AVX_11192019_IDC_Low_Inductance-1667755.pdf they don't...

did some more probing. it appears to be a single interdigitated capacitor instead of an array of 4. that helps explain the high capacitance.

I was able to get a reading on a different one. 2.75uf. that's huge for such a tiny cap! it's .8mm by 1.6mm which would make it 0306 package. I don't know that i've ever seen anything that small with a capcitance over .47uf

Anyone know what values the caps are on the bottom of the Epyc cpu packages? I bought a few duds off ebay with the hopes of repairing them. My meter however is not sensitive enough to read a value on the cap array which makes me think it must be in the PicoFarad range.

How'd I do? A little dented on the outside. looks great on the inside. 1mm taller and it wouldn't have made it in my apartment.

ok I found the last 3 on ebay. hopefully 2.4foot is long enough

damn looks like that site's payment thing is borked

Thanks! it was difficult finding one that was long enough, but I think this should work then? https://overallcable.com/product/sas4-0-slim-line-sff-8654-to-sff-8087-internal-mini-sas-cable/

I have a MZ32-AR0 rev 3.0 board and 6 wd 20tb drives coming in. my case is a 2U 12 Bay Server Chassis CSE-826A-R920LPB IPASS backplane https://www.gigabyte.com/Enterprise/Server-Motherboard/MZ32-AR0-rev-30#Overview https://www.supermicro.com/en/products/chassis/2u/826/sc826ba-r920lpb the...

I would put a 1.8v TVS diode on there so that if the voltage spikes it gets pulled to ground

That's very interesting. anyone able to pull a model number off the u4-u6 chips? if it's something available at digikey, arrow, mouser, octopart etc I wouldn't be afraid to replace them. anyone have any out of warranty dead boards they want to sell me?

what in particular is fragile? I was just thinking of getting one

Can you elaborate on that? I'm curious

it's not. I wish I had the cash for that many gpus. I think I'm just going to wait on OAM and upgrade my motherboard after

for instance if one of the pads or pins on the memory bus is broken or not making good contact, maybe even just plain dirty you could get code 55 for memory even though it might not be on the memory side it could be on the cpu.

doesn't that depend on how it's broken? like if something was wrong with the memory controller on the cpu package it would in theory stop at a code that indicates it couldn't access memory

In case anyone else needs the same info I found this https://forums.servethehome.com/index.php?threads/used-epyc-7601-post-code-78.29841/ "code 78 on an Asrock Rack EPYCD8-2T" "I wanted to implicate POST code 78 (at least on Asrock and other AMI Aptio V based boards) to this exact problem to...

oh no.... That's not what I wanted to hear lol
